Answer:
<em>y = - </em><em> cos ( </em>
<em> x ) , y = cos ( 3x ) + 2 </em>
Step-by-step explanation:
<u><em>Image 1.</em></u>
The graph is reflection of cosine over x-axis and max is 3.5 ⇒ A = -
Period is ( 4 π ) ⇒ B =
There are no horizontal and vertical shifts ⇒ C = D = 0
<em>y = - </em><em> cos ( </em>
<em> x )</em>
<u><em>Image 3.</em></u>
The graph of cosine shifted 2 units up only ⇒ D = 2 , C = 0
Period of the given function is ⇒ B = 3
<em>y = cos ( 3x ) + 2</em>
